Abstract

A computer simulation of reverberation from a moving sea surface for hydrophones 320 m deep is used to compare time and ensemble averages. Reverberation is calculated for a fully developed sea from velocities of 5. 1 and 10. 3 m/sec. For a given mode of reducing the reververation, the derived process is found to be not stationary, but instead behaves like a narrow-band noise of constant amplitude and random phase. Backscattering strengths of sea surface are compared with experimental data.
